.The `firewall` RHEL system role reports `changed: True` when there were changes applied During playbook processing, the `firewall_lib.py` module from the `firewall` RHEL system role was replacing the `changed` message with `False` when using the `interface` variable in the playbook and a pre-existing networking interface on the managed node. As a consequence, `firewall` reported the `changed: False` message even when there had been changes done, and the contents from the `forward_port` variable were not saved as permanent. With this update, the `firewall` RHEL system role ensures the `changed` value is not reset to `False`. As a result, the role reports `changed: True` when there are changes, and `forward_port` contents are saved as persistent.
